Prevention of Stroke Recurrence and Disease Progression in Cerebral Small Vessel Disease With Cilostazol

Sponsor: First Affiliated Hospital of Chengdu Medical College

Summary

This study is designed to evaluate whether cilostazol, an antiplatelet medication, is more effective and safer than aspirin or clopidogrel in preventing recurrent strokes and slowing disease progression in patients with cerebral small vessel disease (CSVD). Cerebral small vessel disease is a common cause of lacunar stroke, cognitive decline, and long-term disability. Currently, aspirin and clopidogrel are widely used to prevent recurrent ischemic events, but their effectiveness in CSVD remains uncertain. Cilostazol has shown potential benefits in improving cerebral blood flow, protecting blood vessel walls, and reducing the risk of bleeding compared with traditional antiplatelet drugs. In this randomized controlled trial, participants diagnosed with CSVD and recent lacunar stroke will be randomly assigned to receive cilostazol, aspirin, or clopidogrel. The main outcomes to be evaluated include the rate of recurrent ischemic stroke, progression of cognitive and functional impairment, MRI markers of CSVD (such as white matter hyperintensity, lacunes, microbleeds, and small infarcts), and safety outcomes including bleeding events. The investigators hypothesize that cilostazol will reduce the risk of recurrent stroke and slow disease progression more effectively than aspirin or clopidogrel, with a comparable or lower risk of bleeding. By comparing these three antiplatelet drugs in a rigorous, multicenter randomized controlled trial, this study will provide important clinical evidence to guide personalized treatment strategies for patients with CSVD. The results are expected to improve long-term outcomes, reduce disability, and enhance the quality of life for stroke survivors.
